Two-Dimensional Monte Carlo Engine
The core innovation of MC2D is its ability to separate variability from uncertainty throughout the entire simulation process. This distinction is critical for transparent risk assessment and regulatory compliance.
Variability (V-dimension)
Natural heterogeneity in populations. Irreducible with more data.
- Individual consumption patterns
- Body weight distributions
- Serving size variability
Uncertainty (U-dimension)
Lack of knowledge about parameters. Reducible with better data.
- Dose-response parameters
- Prevalence estimates
- Measurement uncertainty
Advanced Distribution Fitting Module
Transform raw data into probabilistic inputs with our comprehensive distribution fitting toolkit. Built on the renowned fitdistrplus package with enhanced usability and visualization.
Data Types Supported
- Continuous data
- Discrete/count data
- Censored data (left/right/interval)
- Expert estimates
Fitting Methods
- Maximum Likelihood (MLE)
- Moment Matching (MME)
- Quantile Matching (QME)
- Bootstrap analysis
Key Diagnostics
Cullen and Frey graph, Q-Q plots, P-P plots, statistical tests (KS, AD, Chi-square), AIC/BIC comparison, parameter uncertainty via bootstrap.
